Problem
The trachea or windpipe is located between the larynx and bronchi and is a flexible structure. The wall of the trachea is supported by the presence of C-shaped hyaline cartilages. Explain the role of these C-shaped cartilages. In your description, make sure you include the significance of the cartilage rings being C- shaped. Does the presence of smooth muscle fibers posteriorly play a role in the activity of the structure that is located behind the trachea as well as in the cough reflex? Explain
